Do Transformers, G1 reissues in particular increase, decrease, or maintain their value? Out of my collection, I have several original 1980's Transformers figures. Jetfire is 99.99% complete and mint with box, Scorponok is 100% complete and mint loose, and I have all five Dinobots that are in top shape, missing a few weapons, and loose, and I have a 100% complete Devestator loose. Plus I have my two Kaltors one is mint with box, one is broken but fixed legs with box both electronics work perfectly. All my other figures are reissues. I have "0" interest in selling any of it, in fact I prefer to add to it and make the collection grow. I currently have 88 figures in the lot and have another 60+ on my wish list. Reason I'm asking is my Dad does not believe me when I tell him the value of these figures. He does not believe me that Transformers increase in value over time, and tells me it's wishful thinking. My question is, do they actually increase, or just maintain value? I know broken ones and incomplete ones decrease value. I'm not collecting in hopes of future investment, just out of pure enjoyment of the hobby and owning toys I grew up with as a child. But what do I tell my Dad? His hobby is electric radio controlled aircraft of which he's been part of the hobby since basically it's birth. He was a publisher of one of the earliest radio controlled model airplane magazines. Do you have same problems with your family? What do you tell your parents when you dump money into these figures and your collection? Do they not believe the in their value? Any suggestions? Tips? What do you tell your folks? How do you prove it?
